IPC: G02F1/133
Filed: 2000-05-08
Abstract: PROBLEM TO BE SOLVED: To relax the complexity of hardware, to reduce a cross-talk, to improve the contrast, to improve a viewing core, and to improve the flexibility in implement, by configuring a driving system out of matrix structuring blocks having orthogonality and moving orthogonality characteristics. SOLUTION: This driving system is a liquid crystal display driving system of all of degrees and dimensions, and is configured from matrix structure blocks having orthogonality and moving orthogonality characteristics. This driving system can be realized by using an efficient digital filter bank system as shown in the figure. The moving orthogonality means orthogonality to a transformation of a matrix in which its own columns are moved. Namely, the moving orthogonality is superposed on a common driving signal. As the result, the structuring blocks become rectangular para-unitary matrices. Due to the moving orthogonality characteristic of these matrices, the structuring blocks are allowed to overlap each other. Therefore, assuming that the matrix is expressed by q×r, q and r integers, and q>r, r can take any integer multiples of q.
